   <code class="varname">{cycle}</code> is used to alternate a set of values.
   This makes it easy to for example, alternate between two or more colors
   in a table, or cycle through an array of values.

  You can <code class="varname">{cycle}</code> through more than one set of values in
  a template by supplying a <em class="parameter"><code>name</code></em> attribute.
  Give each <code class="varname">{cycle}</code> an unique <em class="parameter"><code>name</code></em>.
 </p></li>
<li class="listitem"><p>
  You can force the current value not to print with the
  <em class="parameter"><code>print</code></em>  attribute set to <code class="constant">FALSE</code>. This would be useful
  for silently skipping a value.
 </p></li>
<li class="listitem"><p>
  The <em class="parameter"><code>advance</code></em> attribute is used to repeat a value.
  When set to <code class="constant">FALSE</code>, the next call to <code class="varname">{cycle}</code> will print
  the same value.
 </p></li>
<li class="listitem"><p>
  If you supply the <em class="parameter"><code>assign</code></em> attribute, the output of the
  <code class="varname">{cycle}</code> function will be assigned to a template variable
  instead of being output to the template.
